Incorrect billing due to Incorrectly cancelling the contract

I have called in to have the Showmax reactivated as it has stopped working and in the process the agent cancelled my account(contract), after all these my account went from a normal premium of (R748.00) to R3449.00, I have called in few times trying to resolve this since the 1st week of July no luck, on the 10th of July they advised me that the query was escalated until today 17th of July the issue is still not resolved. I have called in asking to speak to the supervisor or team-lead but the agent advised that he couldn't do out bought calls or transfer to the team-lead. I'm very disappointed with how Multichoice is handling my query, I mean this issue was due to their staff's negligence or incompetency or maybe both.

This is unacceptable and pathetic to say the least. They must get their systems in place and provide a better service, I mean we are paying for these services in not like we are getting them for free.
